I’ve made some progress but haven’t yet been able to duplicate this issue.
What I’ve done is taken a fresh WordPress install and installed it locally on one of my machines. I then installed each of the plugins you have listed and after installation and activation, logged out of the dashboard and logged back in again.
One of the plugins, Disqus, I wasn’t able to test fully as the Disqus web service will only work with publicly facing WordPress installs, and as my test installation is behind my firewall on a local machine, Disqus can’t “see” localhost.
One other point of note; a lot of the plugins you’re using either double up functionality (such as Better Author Bio and WP Biographia) or partially double up functionality (such as All In One SEO Pack and Meta Tag Manager); this isn’t a problem per se, but you probably don’t want two biography plugins or meta-tag manager plugins active at the same time.
Also, I’ve noticed that a lot of your plugins aren’t compatible with WordPress v3.3 … Akismet, Better Author Bio, Disqus, Global Translator, Health Check, Landing Sites, Meta Tag Manager, PodPress, Referrer Detector, RefTagger, RSS Syndication Options, Share This, Subscribe Remind, Theme Preview, WP Mobile Detector and WP Super Cache are all compatible with WordPress v3.2.1 and earlier but not v3.3. This isn’t necessarily a problem but it does introduce another level of testing problems.
I used the Better Plugin Compatibility Control plugin (https://www.ads-software.com/extend/plugins/better-plugin-compatibility-control/) to get this information; I know it’s adding another plugin into the mix but I made sure I couldn’t replicate the problem both before installing this plugin and after deactivating and removing the plugin.
Finally, while installing and taking the minimum or default configuration for all of these plugins hasn’t reproduced the problem, that doesn’t mean that some of your site specific settings might not exhibit the problem, but without seeing a complete clone of your site, I can’t even start to test for this. Also, as your theme is a premium/paid theme, this means I can’t test compatibility here either.
So what I suggest is the following:
Make a clean local install of your site; install WordPress v3.3 on a machine which isn’t your public web server. Export your post content and users from your public site and import it into the local install.
Then add and install each plugin, (the order isn’t important, the order you’ve listed them in is as good as any) but still use the default WordPress theme, not your premium/paid theme. For each plugin’s installation, log out and log back in again, configure the plugin to match the settings from your live site and then, again, log out and log back in again.
Finally, if you’re not able to duplicate the problem, then install your premium/paid theme and see if this duplicates the problem.
Let me know how you get on …
